摘　　要：以车身部件翼子板为研究对象,运用Hyperworks软件对其进行有限元分析。将翼子板CATIA模型导入专业网格划分软件Hypermesh并进行几何清理,之后以壳单元为基本单元,对模型进行网格划分。在此基础上,运用求解器OptiStruct对翼子板进行结构分析和模态分析。根据分析结果,针对翼子板局部应力较大的现象,提出了增加加强筋的结构改进建议。Based on the study ofthefenderflap ,part of car-body,the method ofelementfinite analysis using Hyperworks is introduced. By means of the professional meshing software ,Hypermesh,the CATIA model of the fender flap is imported and cleaned up geometrically. Taking shell as the basic element, the model is meshed. After that,the structural and modal analysis of the fender flap are taken ,using the OptiStruct solver of Hyperworks. Finally,as for the fact that some part are not hard enough,the advice of ading reinforced structure is provided.
